Samba 4 missing vfs module and library

Hi, I´m building my own snapshot on bananapi r2 hardware along this checklist:
Sinovoip Forum.
In menuconfig I added samba4-server, samba4-utils, common vfs modules, avahi and netbios support (among others)
After successful build I found samba4 not working. In system protocol I found this line:
Error loading shared library
and other lines regarding to missing vfs.
After removing samba4-server and manual install via luci/opkg the missing modules were added to the device and samba 4 was working well.
Any advice whats going wrong or what I missed in config?
